On Apple platforms, we generate .apple_names, .apple_types,
.apple_namespaces and .apple_objc Apple accelerator tables for DWARF 4
and earlier. For DWARF 5 we should generate .debug_names, but instead we
get no accelerator tables at all.
In the backend we are correctly determining that we should be emitting
.debug_names instead of .apple_names. However, when we get to the point
of emitting the section, if the CU debug name table kind is not
"default", the accelerator table emission is skipped.
This patch sets the DebugNameTableKind to Apple in the frontend when
target an Apple target. That way we know that the CU was compiled with
the intent of emitting accelerator tables. For DWARF 4 and earlier, that
means Apple accelerator tables. For DWARF 5 and later, that means .debug
names.

A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the tenth batch of tests being updated (there are a
significant number of other tests left to be updated).
This changes the current default behavior (from emitting pubnames by
default, to not emitting them by default) & moves to matching GCC's
behavior* with one significant difference: -gno(-gnu)-pubnames disables
pubnames even in the presence of -gsplit-dwarf (though -gsplit-dwarf
still by default enables -ggnu-pubnames). This allows users to disable
pubnames (& the new DWARF5 accelerated access tables) when they might
not be worth the size overhead.
* GCC's behavior is that -ggnu-pubnames and -gpubnames override each
other, and that -gno-gnu-pubnames and -gno-pubnames act as synonyms and
disable either kind of pubnames if they come last. (eg: -gpubnames
-gno-gnu-pubnames causes no pubnames (neither gnu or standard) to be
emitted)
